Supporting context
The article uses a viral classroom video as an analogy for AI prompting: a kindergarten teacher followed her students' sandwich instructions literally, exposing omitted steps that adults assume are obvious. Kamil Banc argues that experienced professionals suffer an 'expert curse' because their tacit knowledge has become invisible to them, making it impossible to translate into explicit AI instructions. He contrasts checklist-oriented roles (engineers, pilots, surgeons, lawyers) with ambiguity-driven roles (executives, marketers, salespeople), suggesting the former adapt to AI more naturally. Practitioners can apply the 'kindergarten test' by writing prompts as if instructing a five-year-old, reading them aloud, and adding a step for every mental 'obviously.' A commenter pushed back, noting that skilled marketers already write detailed briefs and should not be lumped into the vibes-based category.
